The general literature on the phonetic correlates of stress agrees that duration, and in stress accent languages, F0 are consistent correlates of stress. However, the role of amplitude changes in the speech signal is more controversial. In particular, the conflicting results of spectral tilt as a correlate of stress have been attributed to the effects of vowel reduction. We examined the stress correlates of duration, overall intensity and spectral tilt in Catalan and Spanish in both accented… Expand

Word-level prominence in Persian: An Experimental Study

  • 2017
TLDR
The findings are phonologically interpreted as suggesting that word-level prominence in Persian is typologically similar to ‘stress accent’ languages, in which multiple phonetic cues are used to signal the prominence contrast in the accented condition, and stressed and unstressed syllables are different from each other even when the word is not pitch-accented.

Stress- and speech rate-induced vowel quality variation in Catalan and Spanish
TLDR
The important individual variation observed suggests that the effect of stress on vowel quality is not conventionalized in Spanish, and the durational difference between stressed and unstressed vowels is smaller in Spanish than in Catalan and less stable. Expand
Phonetics of Tongan stress
In this study, we determine the acoustic correlates of primary and secondary stress in Tongan. Vowels with primary stress show differences in f0, intensity, duration, F1, and spectral measuresExpand
Stress correlates and vowel targets in Tongan
In this study, we determine the acoustic correlates of primary and secondary stress in Tongan. Vowels with primary stress show differences in F0, intensity, duration, F1, and voice quality, but F0Expand
The role of lexical stress on vowel duration and vowel space in two varieties of Spanish
This paper investigates the effects of lexical stress on vowel durations, vowel space and vowel quality in Spanish. Data come from oral productions of 22 Spanish speakers (10 from Madrid and 12 fromExpand

A Stress “Deafness” Effect in European Portuguese
TLDR
The results show that vowel reduction appears to be the most robust cue for stress in EP, which has implications for claims of a prosodic-based cross-linguistic perception of word stress in the absence of vowel quality, and for stress “deafness” as a consequence of a predictable stress grammar.

Prominence Contrasts in Czech English as a Predictor of Learner’s Proficiency
The study investigates prominence patterns in Czech-accented English comparing the production of non-native speakers of English at two distinct stages of phonological acquisition (beginners andExpand
Effects of stress and speech rate on vowel quality in Catalan and Spanish
TLDR
This study examines the effects of lexical stress on vowel quality in Iberian Spanish and Central Catalan and the relationship between phonetic variation caused by stress and speech rate and concludes that unstressed vowels are characterized by lower F1 than their stressed counterparts. Expand
Acoustic correlates of lexical stress in Uyghur

Catalan speakers' perception of word stress in unaccented contexts.
TLDR
Examination of the perception of word stress by speakers of Central Catalan provides cumulative evidence that word stress is perceived independently of pitch accents by relying on a set of cues with trading effects so that no single cue, including formant frequency differences related to vowel reduction, is absolutely necessary for stress perception.

DISENTANGLING STRESS FROM ACCENT IN SPANISH: PRODUCTION PATTERNS OF THE STRESS CONTRAST IN DEACCENTED SYLLABLES *
According to Sluijter and colleagues (1996a, 1997), stress is independent from accent because it has its own phonetic cues: stressed vowels are longer and have flatter spectral tilts than theirExpand
Perceptual Evidence for Direct Acoustic Correlates of Stress in Spanish
We provide evidence for the perception of the stress contrast in deaccented contexts in Spanish. Twenty participants were asked to identify oxytone words which varied orthogonally in twoExpand
Spectral balance as an acoustic correlate of linguistic stress.
TLDR
It is shown that the intensity differences in the higher regions are caused by an increase in physiological effort rather than by shifting formant frequencies due to stress, and duration proved the most reliable correlate of stress. Expand

TLDR
The acoustical correlates of stress and accent in American English (AE) are reconsidered and an analysis of the strength of the parameters is offered in an attempt to optimally distinguish initial and final stressed tokens by machine, using LDA. Expand
The perception of lexical stress in Spanish
As in other languages, stress in Spanish is signaled by three simultaneous acoustic cues: fundamental frequency (F0), duration and intensity. In this experiment, the role of these parameters in theExpand
Interaction between duration, context, and speaking style in English stressed vowels
Acoustic observations are reported for English front vowels embedded in a /w—l/ frame and carrying constant main stress. The vowels were produced by five speakers in clear and citation‐form styles atExpand
Comparing the 'MagnifyingLens' Effect of Stress to that of Contrastive Focus in Spanish
Stress, which is the linguistic property that makes a syllable in a word more prominent than others, has been defined as ‘localized hyperarticulation’ (de Jong 2004). Hyperarticulation is a termExpand
